采用混凝土护坡是嫩江干流堤防工程建设中经常采用的护坡方法，随着１９９８年持大洪水的退却，各地相应加大力度，对堤防进行防护，由于嫩江干流堤防大多为沙堤砂基，所以混凝土护坡是一种行之有效的护坡方法，但施工中如果处理不好，坡面混凝土的施工质量，很容易造成工程质 The use of concrete slope protection is the most commonly used method of slope protection in the construction of embankments of Nenjiang River. With the retreat of major flood in 1998, all localities should intensify their efforts accordingly to protect dikes. Because most of the embankments of Nenjiang River are sandy sand bases, Slope protection is an effective slope protection method, but if the construction is not properly handled, the construction quality of slope concrete is likely to cause engineering quality
